TheSasks,
I'm just curious, but do you still run the "C" rated tires? The reason I ask is I'm planning on going up to a "D" or maybe even an "E" rated tire when I change them out. I wouldn't think the stiffer sidewall would make that much of a difference.

I still have the factory installed Duro LR C tires all at a TPMS monitored 50 psi (they have over 12,000 miles now) but they are going to be replaced with LR D or E tires in the spring. So ya it's not the tires. The one interesting thing is the first summer we took a 4000 mile trip to Ontario via the Canadian route and there were a couple places that there were huge bumps that were not marked one in particular I hit hard enough that it wedged the rear screen door in the frame but there was not a single thing out of place in the trailer. That episode caused me to sing the praises of the torsion suspension but then this year with far better roads IMO we had all this damage so I am at a loss to explain it. When Dunnnc made his initial post about his shock install I was pretty vocal about not requiring it on these units mostly from a handling perspective as our trailer tracks like it's on rails but I am now of the belief that his mod may indeed help the issues we had as much if not more than the handling. I am not saying it does not aid the handling as in a 5ver with the extra height as it probably does. So I do stand corrected in my opinion of the shock install.

This is the first trailer I've had with torsion suspension and I find it really good I like how it is lower I feel the lower centre of gravity helps stabilize the trailer, as for stuff breaking off with the ride I'd be more inclined to check tire balance than blame the torsion suspension.

Sorry, all my tires were just balanced prior to departure this summer.

They can. I own a wakeboat, lots (way to much) money on a steel trailer. Torsion axles. Lots of guys to taller tires, lower profile and therfore shorter sidewalls. They ride rougher.

Many guys have gone to higher load range as well, again they can tell the trailer rides rougher.
